Slide body

Abstract

A slide body with a top end and a bottom end including a bed portion and sidewalls disposed beside the bed portion respectively on opposite sides thereof. Each sidewall includes an upper portion extending from the top end toward the bottom end, and a lower portion extending from the bottom end toward the top end. The bed portion has a profile substantially defining a path taken by the user sliding from the top end to the bottom end. The upper portion of each sidewall extends above the profile at least a first predetermined distance along a selected length of the upper portion, and the lower portion of each sidewall extends above the profile at least a second predetermined distance along a selected length of the lower portion. The first predetermined distance exceeds the second predetermined distance by a ratio of at least about 2:1.

1 . A slide body for a user to slide thereon, the slide body having a top end and a bottom end, the slide body comprising: 
 a bed portion comprising an upper surface adapted for sliding thereon, the bed portion being defined by the upper surface and a lower surface disposed opposite to the upper surface;    two sidewalls disposed beside the bed portion respectively on opposite sides thereof;    each said sidewall comprising an upper portion extending from the top end toward the bottom end, and a lower portion extending from the bottom end toward the top end;    the bed portion having a profile substantially defining a path taken by the user sliding from the top end to the bottom end;    the upper portion of each said sidewall extending above the profile at least a first predetermined distance along a selected length of the upper portion;    the lower portion of each said sidewall extending above the profile at least a second predetermined distance along a selected length of the lower portion; and    the first predetermined distance exceeding the second predetermined distance by a ratio of at least about 2:1.    
   
   
       2 . A slide body according to  claim 1  in which said two sidewalls are integrally formed with the bed portion.  
   
   
       3 . A slide body according to  claim 1  additionally comprising at least one longitudinal rib projecting from the lower surface, for strengthening the bed portion.  
   
   
       4 . A slide body according to  claim 3  in which said at least one longitudinal rib extends substantially from the top end to the bottom end.  
   
   
       5 . A slide body according to  claim 3  in which said at least one longitudinal rib is integrally formed with the bed portion.  
   
   
       6 . A slide body according to  claim 3  comprising two longitudinal ribs spaced apart from each other for strengthening the bed portion.  
   
   
       7 . A slide body according to  claim 3  in which said bed portion has a thickness defined by the upper surface and the lower surface of substantially 4.6 millimetres (0.180 inches).  
   
   
       8 . A slide body according to  claim 1  in which the profile is substantially sinusoidal.  
   
   
       9 . A slide body according to  claim 1  in which each said sidewall additionally comprises a middle portion disposed between the upper portion and the lower portion.  
   
   
       10 . A slide body for a user to slide thereon, the slide body having a top end and a bottom end, the slide body comprising: 
 a bed portion comprising an upper surface adapted for sliding thereon, the bed portion being defined by the upper surface and a lower surface disposed opposite to the upper surface; and    at least one longitudinal rib integrally formed with the bed portion and extending from the top end to the bottom end, for strengthening the bed portion.    
   
   
       11 . A slide body according to  claim 10  in which the bottom surface is substantially sinusoidal from the top to the bottom.  
   
   
       12 . A slide body according to  claim 10  in which the bed portion has a thickness defined by the upper surface and the lower surface of substantially 4.6 millimetres (0.180 inches).  
   
   
       13 . A slide body according to  claim 10  comprising two longitudinal ribs spaced apart from each other for strengthening the bed portion.  
   
   
       14 . A slide body according to  claim 10  additionally comprising: 
 two sidewalls disposed beside the bed portion respectively on opposite sides thereof;    each said sidewall comprising an upper portion extending from the top end toward the bottom end, and a lower portion extending from the bottom end toward the top end;    the upper surface of the bed portion having a profile substantially defining a path taken by the user when sliding from the top end to the bottom end;    the upper portion of each said sidewall extending upwardly from the profile at least a first predetermined distance along a selected length of the upper portion;    the lower portion of each said sidewall extending upwardly from the profile at least a second predetermined distance along a selected length of the lower portion; and    the first predetermined distance exceeding the second predetermined distance by a ratio of at least about 2:1.    
   
   
       15 . A slide body according to  claim 14  in which said two sidewalls are integrally formed with the bed portion.
